iMPRovEo CUTTING, PUNCHING, AND BENDING MACHINE..

Specification forming part of Letters Patent No. 42,325, dated April 12,1864.

To all zzn/tom, it may concern.- v

Be itknown that I, CHARLES VVRIGHLof the city of Newark, in the county of Essex and State ot' New Jersey, have invented an.A Improvementin Machines forGutting, Punching. and Bending Sheet Metal;` and I do hereby declare the following to be afull and exact description of the same,y reference being herein had to the drawings which accompany .this specification, making partei' the saule.

The nature of. my improvement consists in a peculiar nia-nner of adjustmentof punches, and in the arrangement and combination of the various parts of the mach-ine.

In the drawings, Figure l is a perspective view of the complete machine; Fig. 2, the cutting parts; Fig. 3, the provision for punching; Fig. 4, the rollers for bending; and Fig.

5, a piece of metal cut, punched, and bended.

The same letters refer 'toy the same parts in each figure. A sheet of metal is placed on the table a,

with its edge close to the guard, and is passed between the rollers C and D. On the outer cdgerof these rollers a steel ring, or, if preferred, a plate of steel, is secured, which form cutters, cutting a strip from the edge of the sheet as it passes between the cutting-rings,

'being shown by the letter e.

At the required distance from the edges of the roller c a series of punches, j', are inserted at requisite distance apart, which enter a series oi'holes, g, in the roller d, which roller answers the purpose of a die. f' The roller c is hollowcd at the ends to admit the ring h, through which ring set-screws1 are put for p the ends ofthe punches to rest upon, and so admit ofthe proper 'adjustment ofthe punches. The rollers @and d are made in two parts, for the purpose of allowing alteration in the width of the strips of.metal by the insertion of co1- lars or rings on the shaft between the tw'o parts of 'eacltrollen as shown by the letter j.' The strips of metal when cut and punched by the rollers c and d pass to theL angular rolls la and Z, and are thereby bended to the required angle,` as at Fig. 5. The requisite relative motion of each part is secured by the gearing in, .and the whole is moved` by a pulley and belt. or by a crank, as at n. r

What I claim and desire toV secure is- 1. The adjusting the punches by means of the loose ring and set-screws, substantially as shown. I

2. Theeutting and punching rollers when constructed, combined, and arranged' substantially asA hereinabove described.

' 3. The combination of the bending-rollers with the cutting and punching rollers, in th( manner and for the purpose specified.

CHAS. WRIGHT.
